W'ILLIAM AUSTIN WILLIAMS, .OF NEWSITE, MISSISSIPPI.

WAGON-BRAKE.

SPECIFICATION forming part of Letters Patent N 0. 739,767, dated September 22, 1903.

Application filed April 9, 1903. Serial No. 151,773.

To all whom it may concern:

Be it known that I, WILLIAM AUSTIN WIL- LIAMS, a citizen of the United States, residing at Newsite, in the countyof Prentiss and State of Mississippi, have invented certain new and useful Improvements in Wagon-Brakes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in automatic wagonbrakes.

The object of the invent-ion is to provide a device of this character which is of simple and comparatively inexpensive construction, which is adapted to 'be readily applied to a wagon and capable of adjustment when the runninggear of the same is changed, and which is durable and very efficient in operation.

With this and other objects in view the in vention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter more fully described, and particularly pointed out in the appended claim.

In the drawings, Figure 1 is a plan view of the running-gear of awagon provided with a brake embodying my invention. vertical longitudinal sectional View through the same.

Referring to the drawings by numerals, 1 denotes a transversely-disposed brake-beam mounted to slide upon the top of the reach and rear hounds of the wagon.- Said beam is guided in its sliding movement by the brackets 2, which are secured by bolts or other fastening means upon the top of the rear hounds. The outer ends of the brake are provided with the brake shoes or blocks 3, which are adapted to engage the hind or rear wheels of the wagon.

4: denotes coil-springs disposed upon each side of the reach. One'end of each of said springs is secured to the brake-beam at a point intermediate its center and end, and the opposite ends of said springs are secured to the rear bolster. These springs exert their energy to force the shoes into engagement with the wheels to break the rotation of the same.

Fig. 2 is a with the wheels.

(No model.)

tidenotes an adjustable connection between the brake-beam and the tongue 11 of the Wagon. The same consists of the sliding bar or rod 6, the link 7, and the yoke 8. The bar 6 is slidably mounted upon the top of the reach of the wagon and is provided with a series of apertures or openings 7, through one of which and a central opening in the brake-beam a bolt 8 is adapted to be passed in order to adj ustably secure said rod to said beam. Adjacent to the front or forward end of said rod a longitudinally-extending slot 9 is provided and through which the king-bolt or couplingpin of the wagon is adapted to pass. The forward end of the rod 6 is formed with a book 10, which is engaged with an eye formed upon one end of the link 7. The eye upon the opposite end of said link is engaged with the yoke 8, the ends of which are secured to the doubletree of the wagon upon opposite sides of its pivot-bolt. The tongue or pole 11, to which the doubletree is pivoted, has a limited longitudinal sliding movement between the-front ends of the front hounds, which are,

connected at the top by the plate 12 and upon the bottom by the plate 13.

14 denotes a guide consisting of a U shaped bolt secured upon the rear portion of the reach and through which the sliding bar 6 passes and is guided.

In the operationof the invention the draft or pull of the team upon the doubletree and tongue of the wagon will force the tongue to the limit of its forward movement, thereby moving and holding the connection 5 and brake-beam 1 in a forward position against the tension of the springs 4 in order to hold the shoes upon said beam out of engagement In descending a hill, or whenever the pull or draft of the team is removed from the tongue, the springs 4 will pull the break-beam 1, the connection 5, and tongue 11 rearwardly and force the brakeshoes upon the beam into engagement with the rear wheels for the purpose of stopping or checking the movement of the wagon.

It will be seen that the brake is exceedingly simple in construction and operation and that the same may be easily attached to the running-gears of Wagons. By providing the adjustable connection between the brakebeam and the sliding connecting-rod the device may be adjusted when the length of the reach is changed.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-- A wagon-gear having, front and rear trucks each provided with hounds, a reach attached to the rear truck, a king-bolt pivoting the reach to the front 'truck, a longitudinallymovable tongue, a doubletree movable therewith, springs connecting the doubletree to the front axle and drawing the tongue rearwardly, longitudinally-disposed guides on the rear hounds, a brake-bar slidably supported on the rear hounds and operating in said guides, springs to move the brake-bar rearwardly to normally apply the brake-shoes thereof to the rear wheel, a slidable bar on the reach adj ustably connected to the brakebar and slidably connected to the king-bolt, a guide 14 on the reach for the rear portion of the sliding bar, a yoke attached to the doubletree and a link attached to said yoke and hooked to the front end of the sliding bar, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
